During the Fall 2010 semester the CDC team has focused on redesigning the mounting and arrangement of the dose controller in order to make it more accessible and aesthetically pleasing. Instead of being positioned directly above the entrance tank, the team envisions the system's components being mounted on a plywood board on the wall of the plant. The lever arm of the dose controller would then be connected to the float in the entrance tank by a simple pulley system in order to couple the elevations of the orifice and the entrance tank water level. The team has selected parts for the design and constructed a prototype in the lab.
